/**
 * Update index settings. Changes dynamic index settings in real time. For data
 * streams, index setting changes are applied to all backing indices by default.
 * <p>
 * To revert a setting to the default value, use a null value. The list of
 * per-index settings that can be updated dynamically on live indices can be
 * found in index module documentation. To preserve existing settings from being
 * updated, set the <code>preserve_existing</code> parameter to
 * <code>true</code>.
 * <p>
 * NOTE: You can only define new analyzers on closed indices. To add an
 * analyzer, you must close the index, define the analyzer, and reopen the
 * index. You cannot close the write index of a data stream. To update the
 * analyzer for a data stream's write index and future backing indices, update
 * the analyzer in the index template used by the stream. Then roll over the
 * data stream to apply the new analyzer to the stream's write index and future
 * backing indices. This affects searches and any new data added to the stream
 * after the rollover. However, it does not affect the data stream's backing
 * indices or their existing data. To change the analyzer for existing backing
 * indices, you must create a new data stream and reindex your data into it.
 * 
 * @see <a href="../doc-files/api-spec.html#indices.put_settings.Request">API
